Pray the Rosary as You Desire
During Advent, which mysteries of the rosary are to be said each day?
You are always free to pray using any mysteries of the rosary you desire. There is no obligation to do all of them, or to follow them in order, although that is what most people do. In Advent and Christmas times, it is traditional to pray the Joyful Mysteries on Sunday, replacing the Glorious Mysteries, in order to focus on the mysteries of those seasons. But this is only a custom, and privately you may pray as you please.
